I'm still running in the payload timeout after 1 Minute.
So I did some investigation about it.
I made the attached payload.txt for testing.
I put the command logger "#### Start Test payload #### at the beginning of the payload and logger "#### End Test payload ####" at the end. So I can examine the syslog what happens during ten payload run.
After approx. 1:30 min bunny.service is running into a timeout
